"you can use wallwisher for:
* Personal note taking
* To-do lists
* Party Invitations
* Feedback Collection
* Wishing people on occasions, like birthdays, anniversaries
* Anything that might need input from a lot of people, eg. a Mac Vs PC wall (that'll be a war, not a wall actually). "
Uses the sticky note concept and looks very promising. Reminds me of when my HSC daughter had Post It Notes all over her walls in her bedroom while doing the HSC.
Even simpler to use than Wallwisher. Paste virtual sticky notes on the virtual corkboard. One useful feature allows you to paste a url address for a link to an image and the image will then show up on the sticky note. You do not need to register
